发明名称 METHOD OF STABILIZING A PORTABLE LADDER
摘要 An improved apparatus and method for stabilizing a portable ladder is provided by this invention. The use of through rung functionality of a portable ladder securing device reduces the probability of a person climbing the portable ladder falling from the portable ladder or a person on the ground from being struck by an object falling from a portable ladder. The apparatus and method include the use of stabilizing arms that are attached to the portable ladder either by a brace or a through-rung component. Furthermore, the apparatus and method include a second section for securing the stabilizing arms either to a nearby stable structure or to an integrated ground spike component. The stabilizing arms are adjustable in length allowing for the proper use of the portable ladder stabilizing apparatus in a greater amount of environmental conditions.
